1991-1996 Impala/Caprice/Roadmaster Radiator with Fans for LS and LT engine swaps
When installing an LS or LT powerplant into a 1991 through 1996 Impala automatic chassis, achieving reliable coolant and transmission cooling without chassis modifications is essential. This unit fits B Body rails and automatic transmission plumbing, installing with OE brackets and factory hose port alignment without trimming or adapters. Precision TIG welded aluminum tanks and a high efficiency core deliver rapid heat rejection and corrosion resistance while keeping weight low. Equipped with dual electric fans, it supplies airflow at idle and in stop and go traffic to prevent heat soak and hotspots in Impala, Caprice and Roadmaster models.
Seamless TIG Welded Aluminum Core Construction
The radiator's tanks and core plates are fused using precision TIG welding, creating a unified structure that resists leaks under vibration and thermal cycling typical of LS and LT engine swaps. This method delivers uniform weld beads free of flux or contaminant pockets, ensuring integrity at every joint. Aluminum's natural corrosion resistance contributes to a longer service life, while its low mass and high conductivity support rapid heat transfer away from the engine. Manufactured locally under strict quality control, each unit meets consistent performance standards before leaving the factory.
Optimized Dual Electric Fan System
Equipped with two high capacity electric fans, this system maintains steady airflow through the core at idle and during slow city driving, preventing heat soak around the engine block. The fans are prewired for a direct connection to the factory harness, eliminating the need for custom wiring or additional relays. By drawing air on demand, they replace the need for a belt driven fan and free up a modest amount of engine power. Real time thermal sensor feedback ensures the fans adjust instantly to cooling requirements, keeping temperatures within optimal range.
Direct Fitment for 1991 through 1996 B Body Frames
Engineered specifically for 1991 to 1996 Chevrolet Impala, Caprice, and Buick Roadmaster models with automatic transmission, this radiator mounts directly to original frame rails using OE brackets. Hose port positions and shroud clearances match factory dimensions, so no trimming or adapter fabrication is required. This precise alignment preserves intended coolant flow paths, eliminating hotspots and ensuring uniform temperature distribution across the core. Installers benefit from reduced labor time and predictable results that conform to the original chassis layout.
Finish Options for Enhanced Durability and Style
Select the natural bare aluminum finish to maximize heat rejection and showcase the metallic sheen, or choose the black epoxy coat to defend against moisture and road debris. The epoxy application process is tightly controlled to ensure even coverage and strong adhesion that withstands repeated temperature cycles. Both finishes preserve core efficiency while extending component life by guarding against corrosion. This choice allows builders to tailor appearance and protective qualities to match vehicle style and operating environment.
